Comparing performance of HyperV and VMware considering network isolation in virtual machines

Cloud computing is the set of resources and services which are offered through the internet. These resources are delivered globally from data centers located throughout the world. Cloud services use virtualisation technology to provide better resource management. The biggest challenge facing cloud computing is security as resources are shared between various users. In addition, recent technological improvements in virtualisation are also the reason for breaches in the security of cloud services. To overcome this problem to some extent, isolation of virtual machines is provided. This will ensure security and protection of applications and cloud services from malicious attacks that arises due to resource sharing in virtualisation. Virtual machines are enabled with VLANs and their performance is measured using benchmarking tools. Network isolation is crucial to enhance the performance of virtual machines present in any hypervisors. Isolation of virtual machines will greatly remove the overheads of one VM influencing the performance of another virtual machine. Results delivered from the tests indicate that there is little difference between the two hypervisors in terms of performance, when they are considered in individual VMs. However, VMware proves to deliver better performance than HyperV. Virtual machine isolation at hardware-level and network isolation is considered suitable to resource allocation for virtual machines and to improve their performances
